Metal contamination of home garden soils and cultivated vegetables in the province of Brescia, Italy: Implications for human exposure

BackgroundFor the past century, ferroalloy industries in Brescia province, Italy produced particulate emissions enriched in manganese (Mn), lead (Pb), zinc (Zn), copper (Cu), cadmium (Cd), chromium (Cr), iron (Fe), and aluminum (Al). This study assessed metal concentrations in soil and vegetables of regions with varying ferroalloy industrial activity levels. MethodsHome gardens (n=63) were selected in three regions of varying ferroalloy plant activity durations in Brescia province. Total soil metal concentration and extractability were measured by X-Ray Fluorescence (XRF), aqua regia extraction, and modified Community Bureau of Reference (BCR) sequential extraction. Unwashed and washed spinach and turnips cultivated in the same gardens were analyzed for metal concentrations by flame atomic absorption spectrometry. ResultsMedian soil Al, Cd, Fe, Mn, Pb, and Zn concentrations were significantly higher in home gardens near ferroalloy plants compared to reference home gardens. The BCR method yielded the most mobile soil fraction (the sum of extractable metals in Fractions 1 and 2) and all metal concentrations were higher in ferroalloy plant areas. Unwashed spinach showed higher metal concentrations compared to washed spinach. However, some metals in washed spinach were higher in the reference area likely due to history of agricultural product use. Over 60% of spinach samples exceeded the 2- to 4-fold Commission of European Communities and Codex Alimentarius Commission maximum Pb concentrations, and 10% of the same spinach samples exceeded 2- to 3-fold maximum Cd concentrations set by both organizations. Turnip metal concentrations were below maximum standard reference values. ConclusionsProlonged industrial emissions increase median metal concentrations and most soluble fractions (BCR F1+F2) in home garden soils near ferroalloy plants. Areas near ferroalloy plant sites had spinach Cd and Pb metal concentrations several-fold above maximum standard references. We recommend thorough washing of vegetables to minimize metal exposure.

Metal Accumulation Profile in Roadside Soils, Grass and Caesalpinia Plant Leaves: Bioindicators

Heavy metals are important environmental pollutants and their toxicity in human, plants and animals have been received much more attention. A study was conducted to investigate the heavy metal pollution of roadside soil, grass and Caesalpinia species of Bagalkot city (India). The highest levels of metal concentration of Pb, Cu, Cd, Mn, Zn, Cr and Ni were found in the samples from very traffic congestion. The soil samples at a depth (0-20 cm) grass leaves and Caesalpinia leaves were taken from different sampling sites viz; S1, S2, S3, S4 and S5 on state high way with high traffic roads passing through Bagalkot (India) were determined by Atomic Absorption Spectrophotometer. Results showed that soil and both grass and Caesalpinia contained elevated levels of the metal. It was found that the primary source of the contamination occurs mainly by the vehicular exhausts. The increased circulation of the toxic metals in soils, grass and Caesalpinia may result in the inevitable build up of such xenobiotics in the food chain. The variation in heavy metal concentration is due to the changes in traffic density and anthropogenic activities. Thus, it is concluded that grass, Caesalpinia and soil samples were used as bioindicators of metal pollution in roadside.

From June to July 2012, the heavy metal contents of Pb, Cd, Cr, Cu, Zn, As and Hg in bivalves and the edible fish in Dandong market were determined by using incomplete digestion - AAS method. The results showed that the enrichment of heavy metals in bivalves was higher than those in fish. Significant differences in metal concentrations were found between the tissues of fish. Cd, Pb and Cr were mainly distributed in the scales and gill of the fish. The content of heavy metals in the edible parts of the fish was far below “the human consumption sanitation standard.” The eating quality was good for the edible part of the fish. The content of Cd in bivalves exceeded “the human consumption sanitation standard.” Bivalves containing heavy metals reduced its value for food and attention should be paid on the results.

Prediction of Degree of Soil Contamination Based on Support Vector Machine and K-Nearest Neighbor Methods: A Case Study in Arak, Iran

The degree of soil contamination in an urban region can be changed by heavy metals. This might result in endangering safety of an urban region. This paper presents an approach to build a prediction model for the assessment of degree of contamination index, based upon heavy metals changes. The heavy metal concentration of Pb, Cu, Ni, Zn, As, Cr and Ni as input was used to build a prediction model for the assessment of degree of contamination. Two prediction models were implemented such as support vector regression (SVR) and k-nearest neighbor regression method (KNNR). A comparison was made between these two models and the results showed the superiority of the SVR model. Furthermore, a case study in Arak, Iran was conducted to illustrate the capability of the support vector machines (SVM) model.

Pb and Cd Bioaccumulations in the Habitat and Preys of Red-Crowned Cranes (Grus japonensis) in Zhalong Wetland, Northeastern China

Pb and Cd concentrations in the habitat and preys of the red-crowned crane (i.e., reed rhizomes and three typical aquatic animal families (Perccottus glehni Dybowski, Carassius auratus Linnaeus, and Viviparidae)) were analyzed to examine the impact of these hazards on red-crowned cranes in northeastern China. Results indicated that Pb and Cd concentrations in the preys of the red-crowned cranes were elevated via food chain. Most of the detected Pb and Cd contents in the sediments were above the natural background level, ranging from 9.85 to 129.72 ppm and 1.23 to 10.63 ppm (dry weight), respectively. Cd geo-accumulation index at all sites were larger than 3, even reached 5.22, suggesting serious pollution in this region. Three common water animal families were detected to contain heavy metals, following the order of increasing concentrations: primary consumers (i.e., Viviparidae and Carassius auratus Linnaeus) < secondary consumers (i.e., Perccottus glehni Dybowski). Pb and Cd concentrations in the buffer zone are significantly higher than in the core area and being elevated in the food chain. The molten feathers of the red-crowned cranes showed the highest toxic metal concentrations of Pb (2.09 to 5.81 ppm) and Cd (1.42 to 3.06 ppm) compared with the feces produced by cranes and residual eggshell left by water fowls. Exceptionally high Pb and Cd concentrations in the cranes and their preys were thought to be associated with their habitat.

Blood Cockle (Anadara granosa) is one type of shellfish which have an important economic value in Indonesia. Semarang waters is one of the location of the Blood Cockle which were allegedly tainted by Pb and Cd. The metal content could be reduced by depuration. This research purposed to determine the content of heavy metal concentrations in Semarang waters and determine the effect of shell length and the length of depuration time on the heavy metal concentrations of Pb and Cd in the A. granosa. This research was conducted on 23 July to 28 August 2010. The method used in this study is description on the preliminary research and laboratory experimental method for depuration. Preliminary research was performed by testing the concentration of heavy metals in water, sediments and soft tissue of A. granosa in the waters of Semarang. Primary research conducted depuration process based on differences size of the scallop shell length ≥ 2.0 cm and < 2.0 cm, and different time depuration treatment, i.e. control (without depuration), 1 day, 3 day, 5 day, and 7 days. According to AAS test results showed, the highest concentrations of Pb and Cd heavy metals in Semarang water respectively at 0.23 ppm and 0.036 ppm, in sediment 1.48 ppm and 0.091 ppm, and in the soft tissues of A. granosa of 0.82 ppm and 0.042 ppm. Depuration process can reduce the content of heavy metal concentrations of Pb and Cd, respectively at 0.37 ppm and 0.051 ppm.

Heavy metal contamination of urban soil in an old industrial city (Shenyang) in Northeast China

The purpose of this study is to investigate the current status of heavy metal soil pollution in one of the cradles of industry in China, the Tiexi Industrial District in the city of Shenyang, Ninety-three soil samples were collected from the top 15cm of the soil layer and were analyzed for heavy metal concentrations of Pb, Cu, Cr, Zn, Mn, Cd, As and Hg. The data reveal a remarkable variation in heavy metal concentration among the sampled soils; the mean values of all the heavy metal concentrations were higher than the background values, and the mean concentrations of Pb, Cu, Cd and As were as high as 5.75, 5.08, 12.12 and 13.02 times their background values, respectively. The results of principal component analysis (PCA) indicate that Pb, Cu, Zn, Cd, As and Hg are closely associated with the first principal component (PC1), which explained 46.7% of the total variance, while Cr and Mn are mainly distributed with the second component (PC2), which explained 22.5% of the total variance. Geostatistical analyses, including the calculation of semivariogram parameters and model fitting, further confirmed the results of the statistical analysis. In the estimated maps of heavy metals, several hotspots of high metal concentrations were identified; Pb and Cu showed a very similar spatial pattern, indicating that they were likely from the same source. There is a clear heavy polluted hotspot of Pb, Cu, Zn, Cd and As in the northeast part of the Tiexi Industrial District because of the Shenyang Smelting Plant, which was a backbone enterprise of China's metallurgical industry. There were also hotspots for other heavy metals in other areas. This is mainly the result of the industrial processing that occurred in the study area. All of these data confirm that Pb, Cu, Zn, Cd and As are a result of anthropogenic activities, especially from industrial processes. For Cr and Mn, the concentration patterns indicate low spatial heterogeneity, with low correlation to other metals, indicating that the concentration of Cr and Mn are mainly caused by natural factors such as soil parent materials. Although the city government of Shenyang has placed a high priority on improving the environment in recent years, it will require a long time to completely eliminate pollution in this area.

Contaminated Sewage Sludge Disposal as a Source of Heavy Metal Bioavailability to Native Plants

The work addresses the issue of heavy metal contamination to the soil by sewage sludge disposal and their accumulation in native plant species in the context of their possible use for sanitation of sludge waste substrates. Total metal concentrations of Pb, Cu and Cd in the soil ranged from 11.85 ± 0.20 to 29.27 ± 0.69, 8.83 ± 0.11 to 26.22 ± 0.40 and 32.75 ± 0.30 to 56.19 ± 0.50 μg/g, while those in plants ranged from Nd to 16.76 ± 0.36, Nd to 15.50 ± 0.23 and Nd to 56.30 ± 0.25 μg/g, respectively. Significant correlations were observed between the soil Pb, Cu and Cd (r = 0.91–0.99, p < 0.0001) while extraction of Cd by Nepeta hindostana and its transfer in shoots was very significant (r2 = 0.92 and 0.84, p < 0.0001, respectively). The highest content of all these metals were noted in N. hindostana with the maximum accumulation for Cd. The study emphasizes that N. hindostana may prove effective in Cd removal from sludge and waste substrates.

Heavy metal pattern and solute concentration in soils along the oldest highway of the world – the AVUS Autobahn

Highways and main roads are a potential source of contamination for the surrounding environment. High traffic rates result in elevated heavy metal concentrations in road runoff, soil and water seepage, which has attracted much attention in the recent past. Nonetheless, investigations of pollutants in roadside soils are still a subject of major interest due to the rapid development of traffic systems and increasing traffic all over the world. The accumulation of the heavy metals Pb, Cd, Cu and Zn in soils along the oldest federal highway of the world has been studied by sampling a roadside transect of 125 by 10 m. In addition, heavy metal concentrations of Pb, Cd, Zn, Cu, Ni and Cr in soil solutions from different distances (2.5, 5 and 10 m) from the hard shoulder of the highway and from three soil depths (10, 30, and 50 cm) were investigated. The results show that heavy metal concentrations are up to 20 times increased compared to the geochemical background levels and a reference site of 800-m distance from the roadside. Soil matrix concentrations in the topsoil (0-10 cm) mostly exceeded the precautionary values of the German Federal Soil Protection and Contamination Ordinance (BBodSchV). The concentrations of Cd, Pb and Zn in the soil matrix tended to decrease with distance from the roadside edge, whereas the concentrations in the soil solution increased at a distance of 10 m onwards due to a lower soil pH. Because of both high pH values and a high sorption capacity of the soils, soil solution concentrations seldom exceeded the trigger values of the German Federal Soil Protection and Contamination Ordinance (BBodSchV) for transferring soil solution to groundwater.

Characterisation, Availability, and Risk Assessment of the Metals in Sediment after Aging

The behavior of metals in sediments after their disposal to land has important implications for the environmental management. The sediment from the Carska Bara (Serbia) was polluted with adequate metal salts in order to reach severe contamination based on the pseudo-total metal content of Pb, Cd, Ni, Zn, Cu, and Cr according to the corresponding Dutch standards and Canadian guidelines. The toxicity and fate of the metal in sediment depend on its chemical form, and therefore, quantification of the different forms of a metal is more meaningful than the estimation of its total concentration. In this study, fractionation of metals in sediment has been investigated to determine its speciation and ecotoxic potential, as well as evaluation of metal potential toxicity based on the simultaneously extracted metals (SEMs) and acid volatile sulfides (AVSs) analysis at the beginning of the experiment and after 5 weeks of sediment aging. The investigations suggest that Cd, Pb, and Zn have a tendency to associate with labile fraction, the most mobile and most dangerous fraction for the environment. Risk assessment code revealed their high risk. Copper and chromium showed low to medium risk to the aquatic environment. Nickel showed no risk to the aquatic environment. This was the case at the beginning and after 5 weeks of aging. Aging yielded an increased mobility of all metals based on the increased proportion in mobile fractions. The Σ[SEMi]/[AVS] ratio was found to be >1 both at the beginning and after 5 weeks of aging, with the ratio showing an increase with time. This ratio indicates the potential availability/toxicity and, according to the US EPA criteria, the samples belong to the group with probable negative effect. If particular metals are considered, only the Σ[SEMi]/[AVS] ratio for zinc was >1 at the beginning. After 5 weeks, the ratio was >1 for zinc, lead, and copper. Comparison of the results of sequential extraction and the results of SEM and AVS analysis showed good agreement for lead and zinc.

In Situ Heavy Metal Accumulation in Lettuce Growing Near a Former Mining Waste Disposal Area: Implications for Agricultural Management

Mining wastes may pose risk nearby urban and agricultural areas. We investigated a lettuce crop land close to a former capped mine tailing in order to determinate the metal uptake by crops. Soil plot sampling design within the crop area and two transects along the tailing were performed. In addition, lettuces (root and leaves) were analyzed after transplant and harvest. The results showed a pH of around 7–8 for all the soil samples. Total metal concentrations were as follows: 190–510 mg kg−1 Pb, 13–21 mg kg−1 Cu, and 210–910 mg kg−1 Zn. Diethylene triamine pentaacetic acid-extractable Pb was around 18% of the total Pb in some samples. Transects along the base and on the plateau of the tailing showed high metal concentrations of Pb (up to 5,800 mg kg−1) and Zn (up to 4,500 mg kg−1), indicating that capping layer had been eroded. Lettuce leaves showed Pb concentrations within standard for human health (<0.3 mg kg−1 in fresh weight). For essential micronutrients such as Cu and Zn, leaves had optimal content (10–28 mg kg−1 Cu, 60–85 mg kg−1 Zn). A continued monitoring in metal uptake is needed in crop lands close to mining wastes in order to prevent risks in food safety. Capped tailings must be monitored and rehabilitation works performed from time to time.

Investigation of environmental contamination in lichens of Gökçeada (Imbroz) Island in Turkey

The main objective of the present study is to determine the type of environmental contamination in lichens in Gökçeada Island in the Northern Aegean Sea in Turkey. We used two different lichen species Cladonia foliacea and Ramalina pollinaria. In the first part of the investigation, the beta activities of lichens have been measured by using a TENNELEC LB 1000-PW detector. The range of beta activity values was between 607 ± 30 and 308 ± 12 Bq/kg for C. foliacea lichens collected from around Tuz Lake and values for R. pollinaria lichens were found to be 740 ± 25 and 541 ± 17 Bq/kg. The second part of the study was concerned with the gamma spectra of the lichen samples measured by using HpGe detector. 137Cs , 134Cs , 40K , 232Th , 226Ra radionuclides were found in C. foliacea collected from around Tepeköy and in R. pollinaria from around Tuz Lake. When these two types of lichens were compared, it was found that R. pollinaria contain more radionuclides. In order to compare and determine which of these lichens act as a better bioaccumulator, K, Mn, Zn, Rb, Sr, Ba and Pb metal content were determined by using Energy Dispersive X-ray fluorescence spectrometry. It was found that C. foliacea collected more Mn and Sr when compared to R. pollinaria.
